Actually I tested AD9524 clock generator for clocking ADC and DAC converters in my radio system. But I need more outputs clock copies for distribution ( more then six). Similar IC to AD9524 is AD9523 with fourteen outputs but is not recomended for new design. AD9523-1 or AD9528 are more complicated (large cases - 72pin, more power, more function and etc...). What is status AD9523? (to use in project or obsolete?).
